Answer:
Undefined slope, vertical line
Step-by-step explanation:
Slope = 
Slope = 
= Undefined
Since the slope is undefined, you would have a vertical line.
The y-coordinate would be 42.
Hexagons have 6 sides. The x-coordinate is the number of hexagons; since our x-coordinate is 7, that means 7 hexagons.
The y-coordinate is the total number of sides. 7 hexagons * 6 sides per hexagon = 42 sides.

Answer:
21 cm by 21 cm
Step-by-step explanation:
The formula for the area of a square is A = x^2, where x is the length of any one side of the square. Here,
441 cm² = x²
This actually has two roots: {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.
The dimensions of the square are 21 cm by 21 cm.
